RESUMO

Introducción: las afecciones quirúrgicas del mediastino son un tema controversial, por la variedad de las manifestaciones clínicas, compromiso de estructuras adyacentes, y complejidad de las intervenciones quirúrgicas a realizar. Objetivos: mostrar la experiencia del Hospital Universitario Cmdte. Manuel Fajardo en la atención a estas afecciones. Métodos: estudio descriptivo, prospectivo, de corte transversal, tipo serie de casos, de todos los pacientes atendidos por afecciones quirúrgicas del mediastino, excluyendo los tumores esofágicos, las hernias hiatales y las prolongaciones endotorácicas de la glándula tiroides. Resultados: la localización más afectada fue el mediastino medio. La enfermedad más frecuente en mediastino anterior fue el bocio endotorácico verdadero; en el medio, el derrame pericárdico agudo y crónico, con compresión del miocardio; y en el posterior, los tumores neurogénicos, las eventraciones y hernias diafragmáticas traumáticas crónicas. Las vías de acceso quirúrgico más usadas fueron la toracotomía anterior izquierda, la esternotomía media, la toracotomía posterolateral y la toracotomía vertical, en ese orden. Las complicaciones más frecuentes fueron la arritmia cardiaca, la inestabilidad tensional y los procesos inflamatorios respiratorios. Conclusiones: las afecciones mediastinales más frecuentes se localizaron en el mediastino medio, posterior y anterior. La cirugía exerética de los tumores y las resecciones del pericardio fueron las intervenciones más realizadas, y las complicaciones más presentadas fueron las cardiovasculares y las respiratorias(AU)


Introduction: the surgical affections of mediastinum are a controversial topic due to the variety of its clinical manifestations, involvement of surrounding structures and the complexity of surgical interventions to be carried out. Objectives: to show the experiences acquired by the Commandant Manuel Fajardo University Hospital in relation to the care of these affections. Methods: a cross-sectional, prospective, descriptive and case-series type study was conducted in all patients seen due to surgical affections of mediastinum, ruled out the esophageal tumors, hiatal hernias and endothoracic extensions of thyroid gland. Results: the more involved location was the middle mediastinum. The more frequent anterior mediastinal disease was the real endothoracic goiter; in the middle, the acute and chronic pericardial leakage with myocardium compression and in the posterior one, the neurogenic tumors, the eventrations and the chronic traumatic diaphragmatic hernias. The more used routes of surgical approach were the left anterior thoracotomy, the middle sternotomy, the posterolateral thoratocomy and the vertical thoracotomy, in that order. The more frequent complications were the cardiac arrhythmia, the tension instability and the respiratory inflammatory processes. Conclusions: the more frequent mediastinal affections were located in the middle, posterior and anterior mediastinum. The exeresis of tumors and the resections of pericardium were the more carried out interventions and the more represented complications were the cardiovascular and respiratory ones(AU)

RESUMO

Optical coherence tomography (OCT) which was brought into existence in early 90s of 20 century is a noninvasive technique for creating cross-sectional images of transparent or semi-transparent internal biological tissue structure.In recent years applicability research in the field of stomatology has made great progress.The micro structure changes of surface layer of the lesions in oral hard and soft tissues could be detected by this technique,with its unique feature to detect insidious secondary caries beneath dental restorations that couldn't be found by current clinical techniques easily.In this review,secondary caries etiopathogenisis and diagnosis,principle were discussed firstly and then imaging observation of OCT to detect early second caries around dental restoration and monitoring on risk factors inducing secondary caries are reviewed.It indicated that OCT technique has great potential on diagnosis of secondary caries.
